Heidelberg International School has been part of the network of Phorms Education since 2009.

Phorms Education celebrates the success of H.I.S. as an IB World School being one of only about 200 schools worldwide offering three of the International Baccalaureate Programmes. It is the only international school within Phorms Education. Since 2006, the organisation has established bi-lingual schools, kindergartens, pre-schools and childcare centres across Germany.

Phorms Education provides the school with administrative services such as accounting, legal advice and IT support.

There are natural links between the H.I.S. philosophy and the Phorms Education network. This is illustrated, for example, by the Phorms mission to create in their students “an awareness for the diversity of languages and cultures”.
